How to turn off the biased locking

My application server is using JDK1.4.2_05, and had been doing well until we upgraded memory from 700M to 1.4G. Ironically, the error message is "OutOfMemory" Exception as following

Exception java.lang.OutOfMemoryError: requested 131072000 bytes for GrET* in D:/

BUILD_AREA/jdk142-update/ws/fcs/hotspot\src\share\vm\utilities\growableArray.cpp

. Out of swap space?

Accroding to the Sun Bug database, this is not a bug. Issue can be resolved by turning off the biased Locking.

"XX:+UseBiasedLocking" is to turn the biased locking on, but how to turn it off? Can I use XX:-UseBiasedLocking?

Thanks

Unfortunately, XX:-UseBiasedLocking is not supported by JDK1.4.x.We identified the services threads that cause locking, and rescheduled those conflicting services threads running in different time slot. Thing became better.Thanksj2xe
